Yes you can.
...but your actual question is probably HOW to do it, right ?

There are several options... Having in mind that you might not have a large amount of projects listed in your CV already (else your question would not be so generic), you should grab some main techniques. Here I have HTML & web server in mind... Ok, so this is how you can do this (not optimal, but suitable for a beginner):
- install web server on RasPi (eg. Apache),
- create main HTML page, containing huge fonts displaying the result,
- this HTMP page needs to have auto-reload attribute set (to eg. 5 seconds, or so - it defines max. latency time),
- create a script which (according to your input, eg. buttons press) increments/decrements/resets/... the result and updates the HTML file.
This is it... launch the web browser with this HTML pase set as a home page and you're done.
The very next thing (version 1.0.1

) which you might do to improve this "system" is to add PHP code into HTML page. PHP code would take care about result data by reading it from a dedicated file. The reason for doing this is to add a simple handling mechanism of simultaneous data update & read, which might occur.
